SNOW-PLOW.

Specification of Letters Patent No. 18,882, dated December 15, 1857.

To all whom it may concern:

Be it known that I, NEWOOMB DEMARY, J12, of Attica, in the county ofWyoming and State of New York, have invented a new and useful Machinefor Removing Snow from Railroad-Tracks; and I do hereby declare that thefollowing is a full and exact description of the construction andoperation of the same, reference being had to the annexed drawing,making part of this specification, in which Figure l is a perspectiveview. Fig. 2 is a view of a part called the rudder.

Fig. 1 represents the machine which is placed upon wheels like a commonsnow plow and is to be attached in the same manner to the front of theengine and to be propelled by it in the same manner, but differing fromthe snow plow in the following points viz: Whereas the snow plow now inuse pushes the snow from the track on either side pressing it togetherleaving it solid and unyielding and making it impossible to pass againafter another fall of snow or a wind. Also crowding the same against thebanks where the road runs below the surface of the earth. Also wheredouble track is laid it pushes the snow from one track to the other.While my snow plow acts so as to cut a square track through the snow alittle wider than the train which is to pass, and it also takes up theentire body of snow from the track and discharges it laterally on top ofthe surrounding snow clear from the track. It can be so constructed alsoas with a rudder under the entire control of the tender who can causethe body of snow thus raised to be thrown to the right or left of thetrack, thereby obviating the difliculty experienced on double tracks andalong side hill cuttings and places where the snow drifts on one side ofthe track.

This machine or shovel consists of the following principal parts, viz,the elevator and the mold board, the rudder and the cutter.

The elevator marked A Fig. 1 consists of a strong smooth faced platformor inclined plane covered with iron or some other metal raised to theproper pitch either in the construction of the frame work or by placinglarger wheels under the hind of the machine or in both these ways. Thisinclined plane is entirely open at the sides behind the cutters and actsas an elevator to elevate the snow from the track. The lower end of theelevator is placed upon the wheels so as to run near the track like thefront edge of the cow catcher. The edge or lower end is provided with aheavy iron bar the front edge made sharp which acts as a cutter at thebottom and by the force of the engine the snow is carried up upon theelevator.

The snow is cut at the sides by the cutter marked E Fig. 1. Theseconsist of two heavy upright bars of iron attached to the front end ofthe elevator one on each corner the front edges beveled. These cuttersare rather an extension of the iron bar running along the front edge ofthe elevator simply turned up at the corners. These cutters are fastenedtogether by an iron rod marked P. Fig. 1 which acts as a brace to thecutters and this bar is also beveled so as to act as a cutter whennecessary. The cutters are also braced by two bars of iron running backand fastening to the sides of the elevator. These braces are marked SFig. 1. These cutters must not extend back along the sides of theinclined plane nor project in front of it because in the former casethey would accumulate the snow in front and in the latter case theywould obstruct its lateral escape from the elevator.

The mold board marked D, Fig. 1 consists of a smooth curved surfaceresembling the two mold boards of a plow placed upon the upper or backend of the elevator one on each side coming together at the center andturning off each way; the point of intersection of these mold boardsbeing fixed at such a point on the elevator that the snow shall beraised up to the level of the surrounding snow before it is pressedlaterally by the mold board. The object of these mold boards is to turnthe snow off from the elevator when it has been raised sufficientlyhigh. The snow is discharged at T, T.

The rudder marked W Fig. l is movable and works something like the helmof a ship. It is hung upon a hinge or heavy upright iron bolt marked Rand is intended to be used whenever it is desired to throw all the snowoff to one side. When the rudder is attached and used it is worked bythe tender standing in the cabin marked I Fig. 1, by a lever marked Nshown in Fig. 2 while he stands upon the floor of the cabin marked M,Fig. 2. The rudder is hung in the center of the inclined plane at thepoint where the wings or mold boards come together and extends to thelower edge of the elevator, and when the snow is not drifted nor anyother impediment in the way the point of the rudder marked C should bedropped into a notch at B, when thus set the body of the snow is dividedand one half falling on the right and the other on the left of thetrain. But suppose the snow to be drifted on the right hand side or aside hill cut where the bank is steep on the right hand side. The rudderis thrown around against the right hand cutter which supports it fromtop to bottom, then you have erected upon the elevator A a breast work,with a smooth surface extending from G to T, T where the snow isconducted and discharged on the left hand side and so it may be shiftedat pleasure.

My inclined plane elevator may be used without the rudder and withoutthe knives or it may be used in combination with them.

Now what I wish to claim as my invention and desire to secure by LettersPatent 1s 1. The combination of the mold board and of the inclined planeelevator open at the sides and so arranged as to elevate the snow fromthe track about to the level of the top of the surrounding snow beforeit is pressed laterally by the mold board.

2. The side cutters E, E, arranged so as 'not'to project in front of theelevator or to obstruct the lateral escape of snow at the side of theelevator in the manner and for the purpose substantially as abovedescribed.
